Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates primarily to packaging for disposable sanitary hygiene products, preferably sanitary napkins, incontinence products, etc., and secondarily to methods for manufacturing such packaging.

Until now, it has been common practice for disposable items such as diapers and sanitary napkins to be loosely packaged in large packages such as plastic bags or cartons.

Of course, this type of packaging is impractical and too bulky if only a few packages are needed for travel. For this reason, one-piece packaging bodies for this type of sanitary hygiene products have recently been developed. This type of one-piece packaging is disclosed in West German Patent Publication No. 3146.
No. 067, one end is folded over the center part.
It is made up of folded plastic film.

The side edges of these end portions, ordered as a result of this folding, are welded together to form a storage pocket into which the folded disposable article can be inserted. The other end of the packaging film acts as a sealing cover to cover this pocket.
This end portion is also welded along its edge to the edge of the pocket. The cover thus produced is provided with a countersunk adhesive bead by which the pocket can be resealed after the package has been opened.

This dress is further intended to constitute a so-called service bag, ie a storage bag for holding used disposable items.

Disposable articles in the form of diapers, sanitary napkins, etc., after absorbing body fluids, change their shape and become damp and clunky, which is why prior art packaging and (or service) This makes it virtually impossible to store it in a bag.

For this purpose, there is a great need for a one-piece packaging bag that can be used as a service bag to store the used item after it has been used. However, hygroscopic disposable articles are relatively bulky, and therefore, it is necessary to make the body as compact as possible, which of course affects the packaging process. However, so far it has not been possible to combine the above objectives with the need to make the package large enough to be used as a service bag for such items.

However, the problems outlined above have been completely solved by the present invention. The main feature of the packaging according to the invention is that the packaging consists of one or more one-piece packets with intermediate perforations, each one-piece packet being designed as a bag of liquid-impermeable material; After opening and removal of the items contained therein, the bag can be stretched by expanding pleats or the like provided in at least one of the walls so that the bag can accommodate the used items.

Some suitable embodiments of the packaging according to the invention are set out in claims 1-2.

The inventive method for manufacturing a package of the above type for disposable sanitary hygiene products, preferably sanitary napkins and incontinence products, is described in claims 4, 5 and 6.

The invention will be described in more detail below with reference to the accompanying drawings.

In Figure 1g1, numeral 1 indicates a sanitary napkin to be packaged, and 2 indicates a plastic film serving as a packaging blank. The sanitary napkin is provided with an adhesive coating that contacts the plastic film and holds the napkin in place on the side facing the wearer's underpants during use. This coating may consist of a hot melt, for example, but is not shown in the drawing.

Up until now, methods of packaging sanitary napkins with adhesive coatings have required the use of release paper that is affixed to the coating.

However, such release paper is somewhat expensive compared to the overall cost of the product.

In the one-piece packaging of the present invention, the plastin strip 2
Substituted with a release coating 3 applied to the paper, this release coating is significantly cheaper than separate release paper and eliminates the inevitable handling and disposal of peeled paper strips.

The plastic piece 2 is transversely in the section 4.5 and in the section 6.
7 extends longitudinally beyond the edge of the sanitary napkin.

As shown in Figure 2, the edge portion 4.5 of the plastic piece 2
is folded around each side edge onto the opposite side of the sanitary napkin l. In the illustrated embodiment, the edges of the side portions folded around the napkin extend generally toward and from each other. The longitudinal beads 8, 9 of tightening agent, preferably hot melt, are then folded into transverse sections 4.5.
When applied close to the edge of the napkin l, the napkin l is folded together with the packaging blank 2 about the lateral center line. This state is indicated by arrow A in Figure 2.

It is shown by B. The two halves produced by the folding are compressed and adhesive beads 8.9 join the napkin and the packaging blank to form a tight packaging. FIG. 3 is a cross-sectional view of this unit. After folding, the packaging unit is preferably sealed by welding both end portions 6.7. The perforation holes 10 are simultaneously provided inside the welded portion.

To remove the napkin 1, it is necessary to tear it along the perforations 10. Owing to the side part 4.5 folded towards the entry side, the packaging blank 2 seals tightly around the napkin l, so that the napkin cannot be immediately pulled out of the opened packaging. Instead, the napkin comes out by turning the wrapper inside out. Folded side part 4
．． The folds of the package wall formed by 5 stretch and widen one after another. As the packaging blank is pulled back from the napkin in this way, the empty packaging blank becomes a bag, which is considerably smaller in size than when it was used as a packaging for napkin 1. big. The resulting bag is large enough to hold used napkins. Therefore, 8g! The body blank 2 is useful not only as a sealed package for a compact package unit, but also as a large service bag for storing used napkins.

Another embodiment of the method of the present invention for packaging sanitary napkins shown in Figures 1g5-8 is similar to the embodiment shown in Figures WiI-4. Accordingly, details mentioned in Figures 5 to 8 are designated by the same reference numerals as corresponding details in Figures 1 to 4.

The only difference between these two embodiments is that the packaging blank 2'' of the embodiment of FIGS. 5 to 8 has a wider width than that of FIGS. 1 to 4. Therefore, Wi5
In the embodiment of FIGS. 8 to 8, not only the side parts 4, 5 are folded over the napkin 1, but also the edge parts 4', 5' are folded outwards towards the edge of the napkin 1. This further folded condition is clearly shown in FIG.

Also in this embodiment, a binder bead 8.9 is applied in the edge area of the side part, more particularly in the outwardly folded edge part 4', 5''.

Due to the double folding of the side [1 part of the packaging blank 2, in the packaging embodiment of FIGS. 7 and 8,
After opening this and taking out the napkin, see Figures 3 and 4.
A bag larger than that obtained with the package shown in the figure is obtained.

In the embodiment shown in FIGS. 9 to 11.

The packaging blank 2 is formed from a continuous web of material that is advanced. This packaging blank 2 is first provided with longitudinal seams and pleats 11 by folding its longitudinal central portion. This folded quag is then coated with a longitudinally applied release strip 3 extending along both sides of the folds and abdominal folds, resulting in an adhesive bead 1.
2. The sanitary napkins l provided with 13 are stacked on the packaging blank 2 at equal intervals. Orientation of folding while using a napkin! The adhesive beads 12, 13, which serve as the primary retainer, are then applied to the adhesive coating 3.

As shown in FIG. 10, the side pieces 14'15 of the package blank extending laterally beyond the napkin are folded around the napkin with their overlapping edges glued by hot melt beads 16. The packaging blank for a large number of napkins is finally welded at 17 between each napkin and separated at the same time to form each 11 napkin.
5! A separate one-piece package, suitably perforated 18, is formed. The 8 compartment can be conveniently opened along this perforation hole to take out the napkin. After removing the napkin, the package can be easily expanded by expanding the folds 11 provided on one wall of the empty bag.

Figures 12 and 13 show two variations of the embodiment of Figures 9-11. The only difference is that the design of the legs and belly folds 11 is different.

FIGS. 14 to 16 show still another embodiment of the S-shaped body of the present invention and the method for manufacturing the same.

According to this embodiment, packaging blanks 2 having relatively wide dimensions are continuously fed along a conveyor belt (not shown), and sanitary napkins 1 arranged at equal intervals are produced as shown in FIG. The binder bead 12 of the napkin is stacked on the packaging blank 2 against the portion of the blank 2 that is coated with a peel-off. After the package has been folded as described above, it is folded together with the individual napkins and separated by cutting between each adjacent napkin in one piece as shown in Figure 15. Form a package.

@ As clearly shown in Figure 15, the bottom part of the packaging blank 2 folded around the napkin extends slightly laterally outward from the top part as shown by numeral 19, and extends to this long part. A hot melt bead 20 is applied.The blank part that extends beyond the napkin is folded onto the napkin, after which the package is affixed by the M melt bead 20.
It is sealed as shown in Figure 6. When opening the package made in this way, a larger bag is obtained which can be used as a service bag for used napkins.

The invention is not limited to the embodiments described above, but numerous variants are conceivable within the scope of the appended claims.

For example, packages similar to the embodiments shown in FIGS. 43 and 4 may be implemented in ways other than those described with respect to FIGS. 1 and 2. If a plastic web with the same width as shown in Figure 1 is used as a substrate with respect to the width of the napkin, instead of folding and sealing the package as described in Figure @2, a very large bag in terms of napkins can be obtained. The wrapper blank and napkin could be folded about the lateral centerline of the napkin and then welded or electrically connected to the side edges of the napkin and the wrapper blank. The bag portion thus extending laterally beyond the napkin can also be folded into the space between the two halves of the folded napkin to achieve a package similar to that of FIG.

To obtain a package of the type disclosed in Figure 3, a folded napkin is inserted completely into the center of the wide bag and the part of the bag extending beyond the napkin is folded between the napkin halves. Of course, this can be achieved by doing this.
